Answer:
y = 2x + 7
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (- 3, 1) and (x₂, y₂ ) = (- 2, 3)
m = [tex]\frac{3-1}{-2+3}[/tex] = [tex]\frac{2}{1}[/tex] = 2 , then
y = 2x + c ← is the partial equation
To find c substitute (- 3, 1 ) into the partial equation
1 = - 6 + c ⇒ c = 1 + 6 = 7
y = 2x + 7 ← equation of line
2/5(25y - 50) + 25y simplified
Answer:
35y - 20
Step-by-step explanation:
Given
[tex]\frac{2}{5}[/tex](25y - 50) + 25y ← distribute parenthesis
= 10y - 20 + 25y ← collect like terms
= 35y - 20

If the midpoints of the sides of ∆EFG shown below were connected with line segments, what would be the perimeter of the resulting triangle? Explain how you arrived at your answer. *
Answer:
17.5
Step-by-step explanation:
I beleive since we are connecting midpoints you divide each side by 2 and add them all up to get the perimeter of the smaller triangle made with the ratio of 1:2
The midpoints of the sides of ∆EFG are connected with line segments, then the perimeter of that triangle is 15.5 cm.
What is the triangle?Triangle is a polygon that has three sides and three angles. The sum of the angle of the triangle is 180 degrees.
Given
If the midpoints of the sides of ∆EFG shown below were connected with line segments.
Then the sides of the triangle get half.
Then the perimeter will be of a new triangle will be
[tex]\rm Perimeter = \dfrac{8}{2} + \dfrac{15}{2} +\dfrac{12}{2}\\\\Perimeter = 17.5[/tex]
Thus, the midpoints of the sides of ∆EFG are connected with line segments, then the perimeter of that triangle is 15.5 cm.

if it takes 3 men 5 hours to dig 12 holes, how many hours does it take for 3 men to dig 84 holes?
Answer:
Hence it will take 35hours
Step-by-step explanation:
Let the time it took to dig hole be x
Ley the number of holes be n
Using the relationship x = kn (direct relationship)
if it takes 3 men 5 hours to dig 12 holes, hence;
when x = 5, n = 12
k = x/n
k = 5/12
To get how many hours it take for 3 men to dig 84 holes, then;
when n = 84, x = ?
x = 5/12 * 84
x = 5 * 7
x = 35hours
Hence it will take 35hours
Which 2 variables are most likely to show a negative correlation when represented on a scatter plot?
Answer:
Water level and temperature
Step-by-step explanation:
Scatter plots are used to graph linear data containing to two variables, with the independent variable on the x - axis and the dependent variable on the y-axis. Linear data graphed on a scatter plot may be positive or negative depending on the type of relationship which exists between the two variables. Positive relationships are represented by positive slopes, with x increasing as y increases. Negative relationship on the other hand results in a reduction in Y as X increases and vice versa. Examples of negative correlation include the association between water level and temperature. ; water level will usually decrease as temperature rises. Therefore, any association between variables whereby a increase in one leads to a corresponding decrease on the other is tagged as a negative correlation.
